What is the EU AI Act?

The EU AI Act is a European Union regulation establishing a risk-based framework for AI systems and, in some cases, general-purpose AI models. It defines categories of AI use and assigns obligations related to safety, transparency, governance, and compliance according to the level of risk.

Who is a provider under the EU AI Act?

A provider is a person, organization, public authority, agency, or other body that develops an AI system or general-purpose AI model, or has one developed, and places it on the market or puts it into service under its own name or trademark.

What is anonymisation in AI data governance?

Anonymisation and de-identification are techniques used to reduce the risk that individuals can be identified from a dataset. In practice, irreversible anonymisation can be difficult, especially when datasets can be linked with other information.

What is AI safety?

AI Safety is the interdisciplinary field and set of practices focused on preventing harm from AI systems. It includes reliability, misuse prevention, bias and error mitigation, alignment with human values, and analysis of both near-term and long-term risks.

How is risk different from harm?

Use risk for potential adverse outcomes before or during assessment; use harm for the adverse effect that has occurred or may be concretely described.

What is a safety case for AI?

An AI safety case is a documented argument, supported by evidence, that an AI system is acceptably safe for a defined use and operating context. It is especially relevant for higher-risk sectors where assurance must be explicit, reviewable, and maintained over time.

What is model drift?

Model drift is the degradation or change in model performance over time as real-world data, user behavior, or operating conditions diverge from the data used during training or evaluation. Detecting drift is important for deciding when to retrain, recalibrate, or replace a model.

What is model evaluation?

Evaluation is the process of measuring the quality, behavior, or performance of a model, system, or change against defined criteria. In machine learning it may use validation and test data, while LLM evaluation may also include safety, factuality, robustness, and user-impact assessments.

How are precision and recall different?

Use Precision when false positives are costly; use Recall when missed positives are costly.

Why can accuracy be misleading?

Accuracy is a classification metric equal to the proportion of predictions that are correct among all predictions made. It is useful in some evaluation settings but can be misleading when classes are imbalanced, where precision, recall, or other metrics may better reflect model performance.

What is an agentic loop?

An Agentic Loop is the repeated cycle through which an AI agent observes a situation, reasons about what to do, acts, and uses feedback to continue or stop. The loop continues until a goal is achieved, a failure condition occurs, or another termination rule is met.
